To celebrate the 50th anniversary of Grateful Dead, the four original members — Mickey Hart, Bill Kreutzmann, Phil Lesh, and Bob Weir — will reunite at Chicago's Soldier Field, nearly 20 years to the day of the last Grateful Dead concert, which took place at the same venue. “Fare Thee Well: Celebrating 50 Years of Grateful Dead" will occur over three nights on July 3, 4, and 5, 2015, marking the original members' last-ever performance together. The band will be joined by Trey Anastasio (guitar), Jeff Chimenti (keyboards), and Bruce Hornsby (piano). The group will perform two sets of music each night.
